Deep below the surface of northern Puerto Rico, lie the impressive Rio Camuy Caves. Formed over millions of years by the Rio Camuy subterranean river, the third longest underground river in the world, the caves really are sight not to miss when visiting the Isle of Enchantment.

Entrance to Cueva Clara

The Rio Camuy Cave Park covers a total area of 268 acres and includes three massive sinkholes. The park’s main attraction is the Cueva Clara, which is 695 feet long and up to 170 feet high.

As with any cave system, visitors must be careful when entering the Rio Camuy Caves. The floor can be uneven in places, so you have to watch your feet, of course.

The ‘Fountain of Youth’ – careful not to drink too much!

But perhaps more significantly, we have to be respectful of the cave and any damage we might do it, no matter how unintentionally. Even the grease from a finger, unsuspectingly left on the surface of a stalactite or stalagmite, can end the delicate process of accumulation, which could have been taking place for tens of thousands of years.

So be Careful Below!

Also be careful not to bump into any of the caves’ inhabitants… like this scorpion spider…shudder!
